[0001] This utility model relates to the technical field of bearing disassembly tools, and in particular to a quick disassembly and assembly tool for roller box bearings. Background Technology

[0002] As a key component in mechanical equipment, the efficiency of roller box bearing disassembly and assembly directly affects the maintenance cycle and production efficiency of the equipment. Traditional bearing disassembly and assembly tools mostly use fixed structures or support devices that require individual adjustment. When dealing with bearings of different diameters, it is often necessary to adjust the position of multiple support legs sequentially, which is cumbersome, time-consuming, and makes it difficult to ensure the synchronization and concentricity of each support point. This can easily lead to bearing misalignment or damage, affecting the stability and service life of the equipment. Therefore, there is an urgent need for a disassembly and assembly tool that can quickly and synchronously adjust the support position to adapt to bearings of different diameters, in order to improve work efficiency and operational safety.

[0003] To address this issue, we propose a quick assembly / disassembly tool for roller box bearings. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick assembly and disassembly tool for roller box bearings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick assembly / disassembly tool for roller box bearings includes a support platform and a positioning pin. A threaded groove is formed at the center of the support platform, and a threaded rod is inserted inside the groove. Four sets of rectangular slide rails are formed on the surface of the support platform, and a first sliding sleeve and a second sliding sleeve are inserted inside each rectangular slide rail. A support leg is fixedly connected to the bottom end of the first sliding sleeve. A support rod is hinged to the bottom end of the positioning pin. A hollow rod is fixedly installed at the bottom end of the support platform, and a limiting sleeve and a movable sleeve are sequentially fitted onto the surface of the hollow rod from bottom to top. The outer wall of the movable sleeve is hinged to the bottom end of the support rod. A handle is fixedly installed on the left side of the support platform.

[0006] Preferably, the outer wall of the hollow rod is provided with an external thread, the inner wall of the limiting sleeve is provided with an internal thread that matches the external thread of the hollow rod, the inner wall of the movable sleeve is a smooth surface, and the movable sleeve and the limiting sleeve are connected by a bearing.

[0007] Preferably, a support rod is inserted inside the rectangular slide rail, and the two ends of the support rod are fixedly connected to the inner walls of both sides of the rectangular slide rail. The first sliding sleeve and the second sliding sleeve are both sleeved on the surface of the support rod.

[0008] Preferably, a fixing post is fixedly installed at the center of the top end of the first sliding sleeve, and a positioning pin is fixedly connected to the side wall of the fixing post.

[0009] Preferably, a measuring ruler is fixedly installed at the top of the support platform at the edge of the rectangular slide rail, and the end of the positioning pin away from the fixed column abuts against the side wall of the measuring ruler.

A support leg 7 is fixedly connected to the bottom end of the first sliding sleeve 10. A support rod 6 is hinged to the bottom end of the positioning pin 13. A hollow rod 4 is fixedly installed at the bottom end of the support platform 1, and a limiting sleeve 5 and a movable sleeve 3 are sequentially fitted on the surface of the hollow rod 4 from bottom to top. The outer wall of the movable sleeve 3 is hinged to the bottom end of the support rod 6. During use, the rectangular slide rails can play a limiting role, which facilitates the linear movement of the rectangular slide rails. A handle 9 is fixedly installed on the left side of the support platform 1.

[0017] Furthermore, refer to Figure 5 It can be seen that the outer wall of the hollow rod 4 has an external thread, the inner wall of the limiting sleeve 5 has an internal thread that matches the external thread of the hollow rod 4, the inner wall of the movable sleeve 3 is a smooth surface, and the movable sleeve 3 and the limiting sleeve 5 are connected by a bearing. During use, rotating the limiting sleeve 5 can push the movable sleeve 3 to move up and down, thereby achieving the adjustment function.

[0018] Furthermore, refer to Figure 2 It can be seen that a support rod 11 is inserted inside the rectangular slide rail, and the two ends of the support rod 11 are fixedly connected to the inner walls of both sides of the rectangular slide rail. The first sliding sleeve 10 and the second sliding sleeve 14 are both sleeved on the surface of the support rod 11. During use, the support rod 11 can play a limiting role to prevent the first sliding sleeve 10 and the second sliding sleeve 14 from separating from the support platform 1.

[0019] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a fixing post 12 is fixedly installed at the center of the top of the first sliding sleeve 10, and a positioning pin 13 is fixedly connected to the side wall of the fixing post 12.

[0021] Furthermore, refer to Figure 3 and Figure 4 It can be seen that there are four sets of support rods 6. The four sets of support rods 6 are inclined from bottom to top and outward. By inclining, the hinge rotation can be better realized, which makes it easier to push the second sliding sleeve 14 to move.

[0022] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, when it is necessary to adjust the distance between the support legs 7, the operator manually rotates the limiting sleeve 5. The limiting sleeve 5 moves up and down along the surface of the hollow rod 4. When the limiting sleeve 5 moves, the movable sleeve 3 can be pushed and pulled up and down. When the movable sleeve 3 moves, it drives the second sliding sleeve 14 to move left and right along the surface of the support rod 11 through the support rod 6. When the second sliding sleeve 14 moves, it can drive the first sliding sleeve 10 to move left and right. When the first sliding sleeve 10 moves, it can drive the support legs 7 to move left and right, which makes it easy to adjust the distance between the support legs 7, so as to adapt to the use of bearings of different diameters. As the first sliding sleeve 10 moves, it drives the fixed column 12 to move. The fixed column 12 drives the positioning pin 13 to move along the side wall of the measuring ruler 8, which facilitates the measurement of the distance moved by the first sliding sleeve 10. The operation is then completed. The above is the complete working principle of this utility model.
